T0 60% whom it may concern:

Be it known that we, MOSES RA TURNER, ROBERT G. KIRBY, and JOHN R. TURNER, citizens of the United States, residing at Adams, in the county of Decatur and State of Indiana, have invented certain new and useful Improvements in Pumps; and we do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.

Our invention relates to that class of pumps which are adapted to be usedwhen submerged; and it consists of certain new and novel features of construction whereby our pump is adapted for use in driven wells from which water or liquids may be pumped with a minimum amount of power, and discharge a continuous flow without harming or damaging effects to the mechanism, as will be more fully described hereinafter.

The object of our invention is to provide an improved pump which is suitable for raising water to considerable heights, which may be used either above or below the liquid, and which combines an air-chamber, the whole capable of being lowered and used as a submerged pump in deep driven wells of small diameter; and with these objects in View we have constructed our pump of few parts and simple design, which is cheaply manufactured and is reliable and durable in use.

Referring to the drawings, Figure 1 represents a vertical sectional view having the airchamber and piston-rods broken above the cylinder. Fig. 2 is a cross-sectional view on the line X X, showing the valve-openings in the ends of the cage. Fig. 3 is a vertical side view of the valve-cage.

In the drawings, A represents the pumpcylinder, having smooth inner surfaces, preferably constructed of tubing, to which is attached at the lower end the cap U, having the check-valve T 5 and at the upper end of the cylinder is attached the cap or head D, having a hole in the center provided with screwpart of the cylinder are openings K, having valve-seats at the inner side of the cylinder, which .are covered by check-valves K, and when desired to use the pump above water suitable pipes may be attached at these valve openings and at the opening at bottom of cylinder and extend down into the water.

The particularly novel features of our pump are the double piston or plunger, comprising the upper plate M and the lower plate M, which have the water-passages L L. The lower plate is secured, by means of screwthreads and the check-nut I, to the pumprod I. A valve-cage P, having apertures R in its sides, is screwed to both the lower and upper plates of the piston, thus connecting the upper plate, by means of the lower one, to the actuating pump-rod. To the upper plate of the piston is screwed a hollow plunger or sleeve WV of such length that when the plunger is at the bottom end of its stroke the hollow sleeve will protrude through the upper cap of the cylinder into the air-chamber. The hollow plunger, where it passes through the upper cylinder-cap, is provided with a leather packing J held in place against the cap by a plate J, secured by suitable screws, which packing allows the plunger to move longi- =tudinally without leaking.

S is a floatingvalve movable in the cage P and guided thereby. This valve has an upper plate S and the lower plate S the two being connected integrally by the sleeve S and a hole through the center of the plates and the sleeve S serves as a water-passage through the valve.

At the upper end of the double-headed piston is a leather packing N, and between it and the cage Pis a washer 0, so that when the cage is screwed onto the plate M the consequent rotarymotion of the cage may not abrade the leather, but will slide against the washer. vided with a packing N and the washer O.

In practical operation, the piston and plunger being at the upper end of its stroke, as in Fig. 1, and about to descend, the valve S will rise and seat against the upper plate of the piston, opening the waterways L in the lower plate, admitting water through the same, and simultaneously closing the openings L in upper plate, thus making the upper plate a suction-valve. As the plunger descends the liquid contained in the lower portion of the cylinder is forced upward by the pressure of the plunger, and passes through the center of the valve, through the passage IV in the hollow plunger, and is discharged through the passage E in the airchamber and upward to the opening provided. While this action is taking place the upper end of the cylinder is having liquid drawn in through the upper valves K, when the piston is ready to return 011 its upward stroke. As it begins this movement the floating valve is seated against the lower head of piston, covering the openings L, thus transforming this lower head into a suction-valve, which in its stroke will draw liquid into the lower end of the cylinder through the bottom checkvalve, and the liquid in the upper end of the cylinder is forcedthrough the openings L into and around the cage, thence through the pas- 1 sage W of the hollow plunger, and outward through the air-chamber and passage E, as in the other stroke, the action being completed as shown in Fig. 1.

It is obvious that many minor changes in the details of construction may be used, and various forms of check-valves may be apapplied, which being old are not claimed, the essential novelty of our invention being the double-headed piston having the internal floating valve, the connected hollow plunger, and adjacent air-chamber, which together effect a valuable improvement in pumps of this class.

Having described our invention, what we claim, and desire to secure by Letters Patent of the United States, is-

In a pump for raising or forcing liquids having a tubular cylinder; the combination with the cylinder, having a suitable checkvalvc'at each end of same 5 ofadouble-headed valve-piston having apertures in each head attached at its lower end to an actuating-rod passing upward through the top of said cylinder to a suitable lever or motor for operating same; a hollow plunger or sleeve connected so as to be water-tight to the upper head of said piston, said hollow plunger being slidable vertically through the upper cap or head of said cylinder, through which plunger the said actuating pump-rod passes and around which and the walls of saidhollow plunger is provided a waterway for discharging liquids; a suitable packing attached to the upper cylinder-head, and around said The lower plate M is likewise pro-- hollow plunger, by which the same is rendered water-tight when making its upward stroke; a floating valve inclosed between the two heads of said double-headed piston covering apertures in either head, guided by means of a connecting valve-cage which forms and is an essential part of said doubleheaded piston, being its connecting-body; an air-chamber attached to the 'upper head of said cylinder, and a discharge-pipe connected to the upper part of said air-chamber, substantially as and for the purpose shown and described.
